Abstract (en)
The present invention relates toa hydraulic force transmission system (100) the elements of which comprising at least one hydraulically operated fluid power device (102) and hydraulic working fluid circuit for supplying pressurized working fluid for the power device, and a control valve device for controlling the flow of the pressurized working fluid into and/or from the power device in the circuit. In the system the dynamical properties of at least one of the elements is arranged controllable such that the dynamic rigidity of the power devicemay be altered.
